Faced with rival Firefox 4's record-setting launch, Microsoft this week argued that it's unfair to grade its Internet Explorer 9 (IE9) against Mozilla's Firefox.



From PCWorld:

A day after IE9's March 14 launch, Microsoft touted the 2.3 million copies that had been downloaded in the first 24 hours. A week later, Mozilla shipped Firefox 4, logging 7.1 million downloads the first day, another 8.75 million the next. The latter exceeded the 2008 record of 8 million that Mozilla set with Firefox 3 in 2008 for the most software downloads in a 24-hour period.

But in a Tuesday blog post , Gavin contended that differences in how the browser makers offer upgrades makes early comparisons meaningless, and that IE9 will only get rolling next month, when Microsoft enables Automatic Updates on its Windows Update service
